For example: 3~70Hz low-frequency flickering light source may cause photosensitive epilepsy; 100Hz flickering light source may cause headache and migraine; 120Hz flickering light source may affect people's emotions, such as boredom and anxiety.

The harm to vision is very obvious. It is necessary to know that the constant stroboscopic change of brightness will affect the eye movement trajectory of people when reading, thereby accelerating eye fatigue and causing visual impairment to decline.
